ALFRED CHRISTENSEN AND CHRIST OVERGAARD, OF COULTER, IOWA.

PERMUTATION-VALVE.

Application filed June 14, 1915.

To all whom it may concern:

Be it known that we, ALFRED CHRISTEN- and CHRIST OvnRcAAno, citizens of Denmark, residing at Coulter, in the county of Franklin and State of Iowa, have invented certain new and useful Improvements in Permutation-Valves, of which the following is a specification.

The object of the present invention is to provide locking means in the form of a fuel cut-off for safe-guarding unauthorized usage of a motor vehicle, said means in the preferred embodiment consisting of a permutationally operated device interposed in the fuel line, so as to interrupt .at will the assage of fuel from the supply tank to the engine, necessitating acquaintance with the combination before again rendering the vehicle operative.

More specifically the invention comprises spaced supports to which the fuel conduit connects and intermediate which are rotatably mounted a plurality of permutation cylinders, said cylinders having passages therethrough adapted only to register with each other and with the fuel line upon disposition of the cylinders in a predetermined relation as may be indicated by indicia thereon.

It is further contemplated to provide the members with suitable interlocking tongue and groove connections designed for the purpose of preventing leakage of the liquid.

For a full understanding of the present invention, reference is to be had to the following clescription and the accompanying I drawings, in which:

Figure 1 is a plan view of a device constructed in accordance with our invention. Fig. 2 is a longitudinal section therethrough, the fuel line connecting with the device being omitted. Fig. 3 is an end elevation. Fig. i is a transverse sectional view taken about on the line 4-1 of Fig. 1; and Fig. 5 is an end elevation of one of the permutation cylinders emploved in this invention.

Throughout the following detail description, and on the several figures of the drawings, similar parts are referred to by like reference characters.

It may be here stated that the invention is illustrated in the drawings in its simplest embodiment, and we desire it to be understood that the mechanism may be made more complicated so as to render it more difiicult to carry out its objects of establishing Specification of Letters Patent.

continuous communication in the fuel line, as by utilizing a greater number of permutation members, only a pair of which are disclosed by the present drawing.

in carrying out the invention, it is contemplated to attach the device on the dash or at any other suitable location of a motor vehicle, which support is indicated in the drawing by the numeral 1, it being desirable, of course, that the valve construction or cut-off be located at a convenient point for access. To the support 1 are connected by means of fastening members 2, spaced supporting or end elements 3 of suitable size and configuration. These supporting members are formed with transverse passages t preferably in alinement with each other and the fuel line or conduit 5 in which the device is interposed leads to the passage Upon the bolt 6 adjustably conalinement or registry with each other and with the passages t of the respective spaced supports 3. When in such alined position, it will be apparent that the fuel may readily pass from the supply tank (not shown) to the motor or engine construction (not shown).

Obviously a movement or rotation of one or both of the permutation cylinders 7 7 a distance equivalent to the diameter of the fuel line passage will interrupt the supply of fuel and necessarily prevent operation of the motor to which said fuel is supplied. In order primarily to prevent leakage of the fuel from the passages through these parts each permutation member is formed at one side with annular concentric grooves 9 and at its other side with annular tongues or projections 10 which seat, of course, in the contiguous grooved face of the adjacent element. The spaced supports 3 are likewise provided with annular tongues and projections to provide the proper interlockithe proper registry of the"passages through thesefditler'ent"parts may beaccomp'lished, "(each of the cylinders is provided with cer- 'iiiigicommunicatingmeans formed'at correfspond1ng distances from the akl'alfcenter .of

ing' arrangement with the ad'j a'centpermutation cylinder, all as most clearly illustrated in. Fig. 2 of the drawing. -Obviously a very tight and leak-proof connection between the elements is thus provided "and wear of the parts which may be incident to the use of the device as well as undesired play between the cylinders may be eliminated by the adjustment'of'thenuts '6 on the axial bolt 6 connecting the members together. p ciently' tight, if'desired, to lock the members 7, 7" from rotation entirelyas when it is unnecessary to'pifovide' against unauthorized tampering with the f'de'vice. "In order that tai'n indicia, suchas'space marks and numerals "indicated generally. at 11 which cooperate with arrows or similar'designations 12"located on the" supports 8. The proper combination "to obtain such registry, of course, is" supposed to be known'only to the "operatorof the vehicle and each'devi'ce built in accordance with. this arrangement may be j provided with a different. permutation combination so as to make difiicult 'to those unfamiliar withsaid combination, the proper setting 'of" the. cylinders to establish com- 'i munication'of the su ly tank with the en- 'gineasdiereinbefore set forth.

Hating thus described the 'inventi'on','wl'1at we claim new, is:
